AOA's Jimin and MONSTA X's Jooheon appeared on MBC's 'Radio Star' on July 22 where the latter expressed his desire to do a rap battle with the former.  However, whenever he caught Jimin's gaze, he seemed flustered, so he couldn't look at her as he rapped the same line over and over again.

He said, "Honestly, I am a fan of AOA as idols.  However, to be honest, they're not good at rapping," throwing a diss at resident rapper Jimin.  However, it just proved to be cute, as you can see in the video above, and Jimin kept laughing because he could not look at her, evoking a lot of hilarious teasing from the other MCs and guests. 

The MCs asked why he couldn't look at her and he proved to really be a fan as he said his face was shaking.  He lastly threw his opinion that she was just known thanks to 'Unpretty Rapstar,' suggesting it was the show more than her actual rapping that had earned her fame, but his fan boy side proved to be too strong in the end.  It must be really conflicting for him to not be a fan of her rapping but a fan of her in general.

She also addressed the comments made by Sleepy last time as he had claimed to have trained the AOA girls in rap before.  She clarified with, "Sleepy taught me briefly.  I learned from QOQ's A-Man for a long time.  I learned from Sleepy for one or two months."
